The lot at 210 Columbus Ave rises 11 stories over New York. It is carried on the public rolls at a market value of $10.0M, and assessed for tax at $4.5M. In the 45 years its record reaches back, the lot has drawn 449 separate government filings.

The documentary life of the address leans hard toward sale: 109 of its 449 records, fully 24%, fall under that one heading. Mortgage (99) and permit (69) trail well behind. No violations stand open against it today.

The pace is anything but even. The record runs hot early and quiets with age, with 2003 its single busiest year.

On the environmental ledger, the building posts an Energy Star score of 61, with a site energy-use intensity of 64.1 kBtu per square foot. Its operations answer for roughly 617 metric tons of CO2-equivalent a year.

Read together — 24% sale, 45 years of accumulation, a parcel of New York — these scattered records compose a portrait of the address that no single page sets out to draw.

$10.0M of New York, written across 449 government filings.
